The magnetostrictive and magnetoelectric (ME) properties of laminate composites of Fe–20at.%Ga and Pb(Zr,Ti)O3 (PZT) have been studied for laminates of different geometries. The results show that (i) a long-type magnetostrictive Fe–20at.%Ga crystal plate oriented along ⟨001⟩c and magnetized in its longitudinal (or length) direction has higher magnetostriction than a disk-type one; and consequently (ii) a long-type Fe–20at.%Ga∕PZT laminate has a giant ME effect, and is sensitive to low-level magnetic fields.
